scrapy and xpath function 'matches' syntax

Question

I\'m running scrapy 0.20.2.

$ scrapy shell \"http://newyork.craigslist.org/ata/\"

I would like to make the list of all links to advertiseme

Answer 1

matches is an XPath 2.0 function, and scrapy only supports XPath 1.0 (which does not have any regular expression support built in). You'll have to extract all the links using a scrapy selector and then do the regex filtering at the Python level rather than within the XPath.
